BALING-PRESS.

' SPECIFICATION forming `part of Letters Patent No. 381,975, dated May 1, 1888.

Application'led January 22, 1887. Serial No. 225,056. (No model.)

To all whom it may concern:

Be it known that I, HARVEY R. WOLFE, of Louisville, in the State of Kentucky, have in vented certain new and useful Improvements in Ealing-,Presses of which the `following is a full and complete specification.

My invention relates to baling-presses, the novel features of which will be more fully set forth. hereinafter.

In the accompanying drawings, forming part of the specification, Figure l is a top plan view of the press. Fig. 2 is a side elevation.

A A are the top and bottom portions of the frame of the press, supported on wheels for transporting it from place to place. B is a plunger moving in the chamber C.V This plunger is controlled by the pitman D, which is pivoted to the rear side of the plunger at 2o d. .The opposite end of the pitman is forked, as shown at d, Fig. 2. The bifurcations of this pitman embrace and are pivoted to the roller E. At the forward end of the frame is aslotted cam, F, pivoted at G by the spindle G', Fig. 2. The slot H may be slightly curved or angular in shape and wide enough to permit the roller E, attached to the pitman, to move freely throughout its length. At each end of theslot is a depression or bearing to 3o receive and hold the roller E. These two bearings and the pivotal point G are in a line, or nearly so. Attached to this cam is an arm or lever, K, by which the cam is swung or rotated on its axis by power.

, L L are setscrews in wings of the cam, and can be adj usted so that as the cam is swung round past a certain point the endof the setscrew will strike the pitman and throw the roller E out of its bearing and leave it free 4o to move to the other end of the slot. Springs M M are arranged on the outside of the frame,

' so as to draw the plunger and pitman backward as soon as the roller is released by being thrown out of the bearing or catch in the slot.

The roller at once passes to the opposite end of the slot. Then, by swinging the lever and cam round to the position indicated by dotted lines, the pitman and plunger areforced for i ward in the chamber U, compressing the hay or other contents. The set-screws having been 5o properly adjusted, the moment the plunger has been forced into the proper point the roller E is released and the springs M M force the plunger back into position for a new stroke.

The chamber C may be provided with a permanent or removable head, against which the contents are pressed; or after the first bale has been pressed it may be used as a head against which the second is pressed, in which 6o case the chamber is made sufficiently long to hold two bales. I then provide a hinged lid or top, O, which fits into the chamber, making it smaller at the end and somewhat funnel` shaped. The outer end of this hinged portion 6 5 is held in by an elastic pressure, produced by springs or blocks of rubber, as shown at P, Fig. 2. This rubber spring is regulated by the set-screw S. As the bale is forced toward and through the smaller end of the 7o chamber, it is still more compressed and affords a yielding resistance or head for the fresh bale being pressed, and is nally pushed out.

R is a hopper or' receiver for introducing 75 l the hay into the press.

I am aware that it is old -in hay-presses to provide a sweep having a transverse slot in which a roller moves and is connected by links and toggle-bars to the plunger, and I do not 8o claim, broadly, such a construction.

I am also aware that it is not new to construct a baling-press with 'the rear end of the pressing-chamber with a hinged portion for con'- tracting the end, said hinged portionbeing operated or held in place by set-screws or the like, and I do not claim such a construction broadly.

Having described my invention, what I claim, and desire to secure by Letters Patent, ge 1s l. In a balingpress,the combination of a slotted reversible cam provided with set-screws, a roller moving in the slot, and a pitman piv= oted to said roller, whereby as the cam is rotated the pitman forces the plunger into the pressingehamber and the set-screws release in combination with e roller in the cam-slot, the roller at any desired point t0 permit it to a pitrnan, and springs t0 force the roller` when Io move to the other end of the slot in the cam released to the opposite end ofthe canrslot.
